To all whom t may concer/n.: n

Be it known that I, Josnrri I. GRDIN, a

clear, and exact description, reference being had to the accompanying drawings. 1

-This invention relates 4to improvements incutting machines, particularly to those which are adapted' for use in cutting food l into strips, Aas noodles, forinstance,

Oneof the objects'of my invention .is the provision of means for regulating the rela-v ytive speed with which the material is fed to the cutters, and the construction of adjusting' mechanism which may beV4 quickly al-f shaft may extend longitudinally of thematered,to vary the depth of cut desired. VMy invention contemplates, also, anv adjusting means which .may be conveniently installed in existing cutting machines.

My invention 1s particularly'applicable tok speed withwhich the material is fed against the rotary cuttingknives. The means for tion, 'as will behereinafterdescribed in'con.

i nection with the embodiment illustrated in kthe drawings. The essential features will.

` ,be summarized in the claims.

i 7 is a view showing the `l feed ,'mechanism removed from' the machine. d Designating the parts shown in the draw- 'bed 10.,

The materialto be cut'maybe heldin enl gagement with the feed roll by a guidefrolll 20, ywhich iscarriedgwithina yoke 21. This yoke in .turn may be pivoted ,at 22'to the v guides y12 and 13 respectively.` `The guide roll is adapted to beheld in engagement Vwithwthe material to .be cut'byl meansof4 a cover 25which ispivoted at 26 to the bed adjacent the upper end of the runway.`V This l, i

veo

coverlmay also lserve as ,a'support for hold-l K ing long strips of'pmaterialV to befcut. Y Tov operate the feed roll lIjhaveshown a worm wheelin the nature lofa tubular memb er which is secured atthe end of ythe feedl roll', and which Vis provided withf teeth for engaging a worm 45 on a shaft 31. This chine. and be supported byfthe bednear the ends of the runway, and be operableby avl` hand wheel 40, rvwhich is 'provided .with a 'handle V41. The wheel 40jserves` as a' fly wheel .and also as a cutting element, as indi- V.cated by the knives 42, which,V are radially mounted on thersideofthe wheeladjacent v the runway'.`

' The Shaft 31,isjpffaatiybesa from umV vteeth in the worm wheel 30,"pas indicated in 5 for enabling the worm 45 to/belprof vided-'with a ypimaiay :of sections having f teeth of different pitch, asind-icated at 46,

47 and 48, respectively.l A. preferred'mannerof securing the jvariable feed is tomake" the threads' single, double and triple`pitch,asindicated inFigs.,

at a, the double at rand b, the tripleat a, b and c, on the sections indicated at 46, A47. and v48 respectively. sition of the shaft 31 with relation to the '2 yand'; thesingle threads beingindicated By'reason of the offset'po# l feed roll, a satisfactory inter-engagement vm'ay'fbey obtained',betweenfthe Qworm' and worm wheel, even'thoughthe teethfon 'the'y various sections are of Idiiferent pitch: l

To enable the feedadjustment to vvbe 'readjj` Y Y ily accomplished, I have ,shown the worm having 'an extension 50f projecting from one adapted to 31.* YA'knob 52 enables the sets'crew to lbe 45 splined, as at 49,' tothe shaft 31, andas Y yendV of `the worm. This extensionmay VbeV threaded ,to receive a''set` screw51fwhich is' engage recesses 53 inthe shaft', v

engagement with another reeesafor Acaiising j a different pitched. sectionto" engage the worm wheel.

v l have described the machine asy equipped withV a manually operable' cutting element but the arrangement of the feed mechanism enhances the adaptability for an electric driving means whichV is directly Aconnected to the shaft 3l. Such an installation is in- .dicated in Fig. 3 wherein the motor is designated 60, and is arranged to operate a belt y6l, which lin .turn vdrives a pulley 62y on the The operation ofa. machine equipped'with 4myin'vention ispas follows: Assuming that `the material to be cut, indicated at 65, 1s

Vplaced in the runway, then whilethe operator holds the guide roll downwardly with one. hand,-he.grasp`s the handle llywith the i lother' and turnsthelwheel 40. y.This rotates the shaft 81,. and .by reason ,of vthe `inter- YV'eng'agementbetweenthe worm and worm wheel'..conneetion,rotates.the feed, roll 14C,

ltlius drawing materialfbetween thefeed and vguide rolls yand forcingit against theycut- 25T ting 'knives on the inner [falce r ofthe lhand wheel. 1

f v`When it is'desiredt vary'the'depth of the rut, the voperator' releases theset screw' 51 fromengagementV with oneV of the notches 53 andslides the worm. along the: shaft 8l. As the worm l5 .is Ymoved along theshaft, the

feed roll rotates untilthe next succeeding section is brought intoengagementwith the .teeth on the worm wheel. ,'lhen the set screw may be turned in the opposite direction .toV engage the adjacent recess,lthus hold' j' ing the worm in the/new position.

llrorn the foregoing description iti will be yseen that Vmy invention provide'sfor an ad- ;-justable feed' whic'hjmayV be quickly and easily varied in accordancewithrthe .depth ofthe cutrequired, ln addition, my in- 'vention may be' easily incorporatedin eX- Visting -machines and be operable .for satisfactorily regulating thel depth fof cut when the mechanism is controlled g either by the yHaving thus.V described my invention Ik hand or byelectricallyoperated means.
